Abstract

PNEUMATSKI POJAČAVAČ, pronalazak se odnosi na pneumatski pojačavač kočnice koji obuhvata jedno kućište (10) u kome je postavljen klip (22, 14, 102), obrazovan od zadnjeg cevastog dela (22) na kome je postavljen spoljni zid (14), i koji pomoću pomerljive dijafragme (12) obrazuje prednju komoru (16), trajno povezanu sa izvorom vakuuma, i zadnju komoru (18) povezanu selektivno sa prednjom komorom (16) ili sa atmosferom ventilskim sklopom (136, 138, 140), aktiviranim upravljačkom polugom (34), koja naleže preko potiskivača (32) na jednu od površina oslone ploče (58) pričvršćene na potisnu polugu (56), povratnu oprugu (150) upravljačke poluge (34) postavljenu izmedju spoljneg zida (14) i potiskivača (32). Ventilski sklop (136, 138, 140) obuhvata prstenastu ploču (138) koja jednim aktivnim delom ukrućenim umetkom (118) sadejstvuje sa prvim ventilskim sedištem (136) obrazovanim na potiskivaču (32), kao i sa drugim ventilskim sedištem (140), obrazovanim na klipu (14). Prstenastu ploču (138) obrazuje jedna savitljiva cevasta dijafragma (114), pri čemu je aktivan deo prstenaste ploče (138) postavljen izmedju dva kraja (112, 116) savitljive cevaste dijafragme (114). Prema pronalasku, prstenasta ploča (138) ima otvore (120) koji omogućuju vezu izmedju prednje komore (16) i zadnje komore (18).PNEUMATIC AMPLIFIER, the invention relates to a pneumatic brake booster comprising a housing (10) in which a piston (22, 14, 102) is arranged, formed by a rear tubular part (22) on which an outer wall (14) is mounted, and which by means of a movable diaphragm (12) it forms a front chamber (16), permanently connected to the vacuum source, and a rear chamber (18) selectively connected to the front chamber (16) or to the atmosphere by a valve assembly (136, 138, 140) activated by a control lever 34), which rests over the pusher (32) on one of the surfaces of the support plate (58) attached to the push lever (56), the return spring (150) of the control lever (34) placed between the outer wall (14) and the pusher (32). The valve assembly (136, 138, 140) comprises an annular plate (138) which with one active part by a stiffened insert (118) cooperates with the first valve seat (136) formed on the pusher (32), as well as with the second valve seat (140) formed on the piston (14). The annular plate (138) is formed by a flexible tubular diaphragm (114), the active part of the annular plate (138) being placed between the two ends (112, 116) of the flexible tubular diaphragm (114). According to the invention, the annular plate (138) has openings (120) which allow a connection between the front chamber (16) and the rear chamber (18).
